Code in DdsDecoder_Initialize() are moved to DdsDecoder_Wine_Initialize().
And DdsDecoder_Initialize() are implemented on top of DdsDecoder_Wine_Initialize().

Hi,

While running your changed tests, I think I found new failures.
Being a bot and all I'm not very good at pattern recognition, so I might be
wrong, but could you please double-check?

Is this still breaking functionality in d3dx10 that previously worked?

My suggestion would be to move the code to DdsDecoder_Wine_Initialize,
update d3dx10 to use this interface if available, then update the
validation in DdsDecoder_Initialize.

[Ziqing Hui]

It breaks loading cube map in D3DX10GetImageInfoFromMemory().

I think a solution is using DdsDecoder_Wine_Initialize() in windowscodecs/imgfactory.c: find_decoder() if DdsDecoder_Initialize() fails, like:

hr = DdsDecoder_Initialize();
    if (FAILED(hr)) {
        DdsDecoder_Wine_Initialize();
    }

(d3dx10 uses CreateDecoderFromStream() to create a decoder, CreateDecoderFromStream() invokes find_decoder())

I was planning to add these code in a future patch. Now we can add it in this patch. What do you think?

I think that's OK. CreateDecoderFromStream can succeed on Windows for
formats native doesn't support, because someone can always install a
new decoder.
